Thermoregulation and physiological responses

This study compared the methods of determining the footwear insulation on human participants and the thermal foot model. Another purpose was to find the minimal number of measurement points on the human foot that is needed for insulation calculation. Bare foot was tested at 3 ambient temperatures on 6 participants. Three types of footwear were tested on 2 participants. The mean insulation for a bare foot obtained on the participant and model were similar. The insulation of warm footwear measured by the 2 methods was also similar. For thin footwear the insulation values from the participants were higher than those from the thermal model. The differences could be related to undefined physiological factors. Two points on foot can be enough to measure the insulation of footwear on human participants (r =.98). However, due to the big individual differences of humans, and good repeatability and simplicity of the thermal foot method, the latter should be preferred for testing.
